PRESSURE-ROLL; RELEASE FOR WRINGEBS.

Specification of Letters Patent.

Application filed March 31, 1916.. Serial No. 88,009.

To all whom it may concern:

Be it known that I, ALBERT E. HonAnAY, a citizen of the United States, residlng at Naugatuck, in the county of New Haven and appended claims.

State of Connecticut, have invented certain new and useful Improvements inPressure- Roll Releases for Wringers, of which the following is a specification, reference being had therein 'to the accompanying dra'w release for wringers; theobject being to providenovel means for releasing the pressure on the rolls in case that the operators hand or any other foreign object, should become accidentally caught between the rolls.

Another and further object of my invention is to provide a clothes wringer in which the top bar thereof carrying the pressure screws, is 'detachably mounted within the frame of the wringer in such a manner that the operator, by striking the releasing spring can release the top bar so as to reducethe pressure on the pressure bar to allow the rolls to separate.

Another and further object of my invention is to provide. a pressure release for clothes wringers'which is exceedingly slmple and cheap in construction and one which can be readily incorporated. in the ordinary construction of clothes wringer, now in use. Other and further objectsand advantages of the invention will be hereinafter set forth This invention relates to a pressure roll and the novel features thereof defined by the" In the drawingv Figure 1, isa side elevatlon of a clothes wringer partly in section, showing the application of my improved pressure release thereto; and Fig. 2, is a top plan view partly in section, showing the manner of mounting one of the pressure springs of the clothes wringer.

Like numerals of reference refer to like parts in theseveral figures of the drawings In thev drawing, 1 indicates the frame of a clothes wringer formed of, slotted side bars 2 connected together at their lower ends by a rod 3 and connecting members 4, and at their .11 per ends by a" detachable top bar 5 which, ts within the slotted end portions of the side bars. 2;

- The n er ends of the side bars are rovided' wit 'U-shaped members 6 extending across the slot on the outer faces of the bars a Patented Mar.- 20, 1917.

shaft 10 mounted in bearings 11 arranged in the slots of the bars 2, the'shaft's 10 and '7 being preferably provided with meshing gears, not shown,'wh1ch are inclosed by gear caslngs 12. Y

r The bearings 11 carry spring supports 13 1n the nature ofplugs which are seated in openings formed. in the bearings, having head portions which are reduced to form a shoulder 14 against which the end of coiled pressure springs 15 are adapted to abut so as to prevent the springs from rotating' Extending from each gear case is an arm 16 having a hooked upper end 17 which extends between the convolutions of the coil spring 15 in such a. manner that when the pressure is released onthe. springs, the gear casings w1ll be raised by the expansion of the sprlngs so as to allow the upper r'oll free movement, so as to release the pressure instantaneously in case of a foreign object being drawn between the pressure rolls] 'Arranged between the side bars of the frame of the wringer is a pressure. bar 18 which is'provided with plates 19 at its ends having depending stud portions 20 adapted to fit with the upper ends'of the coil springs. 15, as clearlyshown in Fig. 1.

The spring supports 13 are'provided with oppositely disposed lugs 13 which fitwithin grooves formed on the walls of the slotted side pieces 2, as shown in Fig, 2, so as to prevent the supports from rotating.

The top bar 5 mounted within the slotted end portions of the side pieces 2' bet'ween the U-shaped members 6 is provided with a. bowed spring 20 having slots 21 through which screws 22 pass for securing the spring in position upon the top bar, said spring resting'upon bearing plates 23 arranged to the inside of the screws 22,215 clearly shown in .Fig. 1.

The ends of the bowed spring 20 are bifurcated and the arms formed thereby are bent to form spaced eyes 24: in which a transversely arranged pin 25 is mounted carrying a collar 26 forming a roller so as to allow the ends of the spring to move freely when the same is elongated by exerting a ressure on the bowed portion thereof.

Secured to each side of the slot of the end pieces is a hook member 27, herein shown having a central web portion forming sockets to each side thereof which arev adapted to receive the outwardly extend1ng ends of the pins 25 so that when the top bar is in position within the slots of the side pieces, the same will be prevented from moving upwardly thereby so as to hold the top bar under normal conditions, in position within the side pieces to form the frame of the wringer.

The top bar is provided with recessed portions adjacent each end in which are mounted boxes 28 having their threaded bores arranged to register with vertical openings formed in the top bar and in which are mounted pressure screws 29 the lower ends of which, are adapted to extend in recesses 19' formed in the plates 19 carried by the pressure bar 18 so that the necessary pressure can be brought to bear on the pressure bar which in turn, through the pressure springs, will exert a pressure on the bearings of the upper roller.

In the construction of clothes thus far described, it will be seen that I have provided a wringer in which the top bar thereof is detachably 'mounted in such a manner that in order to release the pressure on -.the pressure rolls, it is only necessary to strike the bowed spring which will elongate the same so as to cause the ends carrying the pins 25 to be moved out of the sockets formed in the. hook members which will allow the bar to move vertically so as to relieve the pressure of the pressure screws on the pressure'bar which in turn, releases thetension of the pressure springs so as to allow the springs to expand and as these springs expand, the gear casings are raised with them by their connection thereto and the upper pressure roll 9 is free to move vertically so that the pressure on any object which has been drawn between the pressure rolls can be instantaneously released, the pressure screws forming stopsfor .wringer I with said hooks. for holding the ends of-the bowed spring when the same bowed spri is elongated, the pins carried by the ends hereof'will be carried out of the sockets to insure the releasing of the top bar.

From the foregoing description, it will be seen that I have provided a pressure release for clothes wringers which is so constructed that the same can be used in connection with any of the well-known forms is subjecteigglto an impact, so that as'the cially adapted to be used in connection with 7 power wringers where the pressure rolls are rotated at a high rate of speed, so that the pressure on. the rolls can be instantaneously released in case of accident.
